A neglected but huge fact: Management and coding didn’t make Flickr valuable; that was done by the 89 million users who contributed their 8 billion photographs. Users are now offered 1 Terabyte of storage for free, but ads will soon infest their accounts. Want to avoid ads? Pay twice the rate of a current Pro Account so you won’t see them. Then there’s the $500 Doublr account.

The Flickr re-do is a marketing triumph and usability disaster. All the marketing blather in the world can’t fix bad design. Images now appear in a previously optional “lightbox” display, a dynamic grid that is visually fatiguing and tough to navigate. Asked to save this photo platform, Marissa Mayer merely turned Flickr into Pinterest.

Tumblr: Watch your back.
